Description

Workpiece support device for tile cutting machine

The invention relates to a tile cutting machine, in particular to a workpiece supporting device of a tile cutting machine.

Since the tile itself has the characteristics of brittle and hard texture, it is not possible to use a general cutting tool when cutting, but a tile cutter designed for cutting the tile must be used. Before operating the tile cutter to perform sawing on the workpiece, the tile is placed on the work platform and abuts against the baffle to position the tile to prevent the tile from moving during the process, and then work by working. The platform pushes the tiles in the direction of the sawing device so that the tiles are cut to the appropriate size by the sawing device during the movement.

However, if the size of the tile is too large or the length is too long, the position of the baffle may interfere with the tile, which is likely to be limited by the size of the workpiece in actual operation and affect the work efficiency.

The main object of the present invention is to provide a workpiece supporting device for a tile cutting machine, which can provide a good supporting effect on a large-sized or long-shaped workpiece to improve work efficiency.

In order to achieve the above object, the workpiece supporting device provided by the present invention comprises a working platform, a baffle, and a positioning member. The working platform has a working plane, and one side of the working platform has a first pivoting portion; the baffle has an abutting plane, and the bottom side of the baffle has a second pivoting portion The baffle is pivotally disposed on the first pivoting portion of the working platform by the second pivoting portion, so that the baffle can pivot relative to the working platform, and when the baffle is in a first position, the baffle The abutting plane is perpendicular to the working plane of the working platform, and can be used to provide a positioning effect on the workpiece of a general size; the positioning component is disposed on the first pivoting portion of the working platform and the second pivoting of the baffle When the positioning member is unscrewed, the baffle can be turned according to actual needs, and the baffle can be positioned after the positioning member is locked.

Detailed construction, features, assembly or use of the workpiece support device provided by the present invention will be described in the detailed description of the subsequent embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

Please refer to FIG. 1 . The tile cutter 10 shown in the figure mainly comprises a water collection tank 12 , a support frame 14 , and a sawing device 16 . The support frame 14 is disposed on the bottom surface of the water collection tank 12 for supporting On the ground, a sawing device 16 is disposed on the top surface of the collecting tank 12 to provide a sawing effect. Since the tile cutter is a conventional technique, the applicant will not repeat the detailed structure and operation principle. Referring to FIGS. 2 and 3 again, the workpiece support device 18 of the present invention includes a work platform 20, a baffle 30, and two positioning members 40.

The working platform 20 is erected on the top surface of the collecting tank 12 by two mutually parallel sliding rails 21, so that the working platform 20 can be reciprocally displaced relative to the sawing device 16. The working platform 20 has a working plane 22 for receiving a workpiece to be sawed. Further, the working platform 20 has two opposite first pivoting portions 24 on a side away from the sawing device 16, in this embodiment, The first pivoting portion 24 is a pivot block, and the outer end surface of each of the first pivoting portions 24 has a positioning screw hole 26.

The baffle 30 has an abutting surface 31 for providing an abutting effect on the sawing workpiece. The bottom surface of the baffle 30 has two opposite second pivoting portions 32. In this embodiment, the second pivoting portion 32 has An inner pivoting arm 33 and an outer pivoting lug 34, wherein the outer pivoting lug 34 has an arcuate slot 35, and the inner and outer pivoting lugs 33, 34 are pivotally coupled to the first of the working platform 20 by a shaft member 36. The pivoting portion 24 enables the baffle 30 to pivot relative to the working platform 20 between a first position P1 and a second position P2 when the baffle 30 is at the first position P1 as shown in FIGS. 2 and 4. The abutting plane 31 of the baffle 30 is perpendicular to the working plane 22 of the work platform 20. When the baffle 30 is at the second position P2 as shown in FIGS. 5 and 6, the abutment plane 31 of the baffle 30 is parallel to The working plane 22 of the work platform 20, and the height of the abutment plane 31 of the baffle 30 will be lower than the height of the work plane 22 of the work platform 20. On the other hand, the top surface of the baffle 30 and the abutting plane 31 of the baffle 30 respectively have a plurality of scales 37, and the scales 37 of the two positions correspond to each other, so that the user can be in the first position P1 or the second position of the baffle 30. P2 can have the same scale 37 for reference.

The positioning member 40 has a knob 42 and a screw portion 44 of the connecting knob 42. The positioning member 40 is disposed in the arcuate groove 35 of the baffle 30 by the screw portion 44 and is screwed to the positioning screw hole 26 of the working platform 20. When the positioning member 40 is unscrewing, the baffle 30 can be pivoted between the first and second positions P1, P2, and after the positioning member 40 is locked, the baffle 30 can be positioned at the first position P1 or Second position P2.

It can be seen from the above that if the size of the workpiece is too large to form an interference with the baffle 30, the user can first loosen the positioning member 40, and then the baffle 30 from the first position P1 as shown in FIGS. 2 and 4. After flipping to the second position P2 as shown in FIGS. 5 and 6, the positioning member 40 is locked, so that the abutting plane 31 of the baffle 30 can be adjusted to match the large-sized workpiece, so that the working plane of the working platform 20 22 can provide a stable supporting effect on the large-sized workpiece. At this time, the workpiece can be pushed by the working platform 20 in the direction of the sawing device 16, so that the sawing device 16 can perform the sawing operation on the workpiece.

On the other hand, in the second embodiment of the present invention, the positioning member does not have to use a knob bolt, and may be replaced by a quick release assembly. In detail, the positioning member 50 has a shaft 52 and an adjusting nut 54. a quick release handle 56, and a pressing seat 58, the shaft 52 is disposed in a through hole 27 of the first pivoting portion 24 of the working platform 20 and an arcuate groove 35 of the outer arm 34 of the baffle 30, and the adjusting screw The cap 54 is screwed to one end of the shaft 52 and abuts against the inner end surface of the first pivoting portion 24 of the working platform 20 . The quick release handle 56 has a cam portion 562 and is pivotally mounted on the shaft 52 by the cam portion 562 . At the other end, the pressing seat 58 is sleeved on the shaft 52 and abuts between the outer arm 34 of the baffle 30 and the cam portion 562 of the quick release handle 56. Thereby, when the quick release handle 56 is pulled upward to release the pressing force of the pressing seat 58 against the baffle 30, the baffle 30 can be pivoted between the first and second positions P1, P2, when the pressing force is fast When the handle 56 is removed to push the pressing seat 58, the baffle 30 can be positioned at the first position P1 or the second position P2.

In summary, the workpiece supporting device 18 of the present invention not only has a simple structural configuration, but also is relatively easy to operate, and more importantly, can provide a good supporting effect on a large-sized workpiece to achieve the purpose of improving work efficiency.
